Cannot Launch Nitro Pro App

[Jake Pereira]

Hello, 

I have an active subscription that I cannot use because my Nitro Pro app will not work on my computer. 

I've uninstalled and reinstalled the application many times and it has not helped fix the issue. When I launch the app, nothing appears. When I click on the Nitro Pro icon from my toolbar, it still does not open. When I hover over the app on my toolbar, a blank white window appears with the title "NITRO PRO (EXPIRED TRIAL)". I try clicking on it to launch the app but still, nothing happens. 

Please help as I'm a paying customer that really likes the tool but is growing more and more frustrated that I cannot access the app. 

Thank you.

Hello @Jake Pereira,

Thank you for reaching out to us through our Community Forums!

This is a common scenario when multiple monitors are being used. When Nitro Pro is opened on a monitor that is later disconnected, it won't default to a current "active" display which causes Nitro Pro to display on the missing monitor. Kindly try these steps:

1. Try rebooting your machine.
2. If not fixed after rebooting, focus on Nitro Pro by clicking on it on the Taskbar. 
3. Press the Windows key + Left/Right arrow until Nitro Pro appears.

 

If the above doesn't help, let us uninstall and reinstall your Nitro PDF Pro 13 by referring to these steps:

1. Download and run our Clean Up utility to uninstall your current Nitro Pro and reboot your machine:

http://install.nitropdf.com/professional_13.53.3.1073/install-cleanup/install-cleanup.zip 

2. After rebooting, download and install the latest version of Visual Studio (vc_redist.x64.exe & vc_redist.x86.exe). Visual Studio 2015, 2017, 2019, and 2022 all share the same redistributable files:

3. Clear all your Downloads folder or delete all downloaded Nitro installers. This step is important because we noticed that if you are saving all the installers and you download them in the same folder (like the downloads folder), the EXE can pick up any MSI installer in that folder and you may pick-up one of the older builds instead of the newly downloaded package.

4. Download and install Nitro PDF Pro 13.53 using the installer from this page:
https://www.gonitro.com/nps/product-details/downloads

If you are getting the 'Nitro Pro Wizard has failed' message using our .exe package, it is because it requires a stable Internet connection to download installation files so please use offline English MSI packages:

x32 https://downloads.gonitro.com/professional_13.53.3.1073/en/retail/nitro_pro13_ba_x86.msi
x64 https://downloads.gonitro.com/professional_13.53.3.1073/en/retail/nitro_pro13_ba_x64.msi

 

To know if you have 32-bit or 64-bit Windows system, please refer to this article:

Important: If you are using Chrome or any of the Chromium-based browsers (e.g., Vivaldi, etc.) and you are unable to access the above installer links, you're more than likely experiencing the results of a new security feature that was silently pushed out to the browsers, which blocks .exe/.msi/etc downloads without any visible error or prompt on the browser's frontend user space. In order to bypass this, please try these steps:

a. Right-click the link you're trying to download, and select "Save link as..."
b. Choose your save location and select "Save"
c. On the bottom edge of your browser window, the Downloads bar should now appear and the file will show up with a red error icon, attempting to block the download. Press the caret button and select "Keep"

5. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number 504945-xxxxxx-389166

6. Turning off User Account Control (UAC) for Nitro PDF Pro 13. Here are two methods that you can follow:

a. Right-click the Nitro shortcut > Properties > Compatibility > Turn off any settings there.

b. 
i. Right-click > Troubleshoot Compatibility > Troubleshoot Program
ii. Check "The program requires additional permissions" > Next > Test the program...
iii. Wait for the program to launch > Next > Yes, save these settings for this program > Close

 Thank you very much in advance and I am looking forward to hearing back from you.

Hi Allain, 

Thank you for the thorough walkthrough. The initial steps did not fix the issue so I had to follow the uninstall and reinstallation steps for Nitro PDF Pro 13 which you outlined above.

It appears to have done the trick! I'm looking forward to using Nitro Pro again. Thanks for your help.
